I was reading The Knowledge and noticed a snippet about the UK’s energy production. As of Saturday, we’ve produced 14.08 terawatt hours of electricity. That feels like brilliant progress.

But the part that really got me was the comparison: “enough to power 5.2 million homes for a year, or the London Underground for a decade.” I’d never thought about how much energy the Underground uses compared to homes. This suggests that 500,000 homes worth of electrical use equates to one year of London Underground use.

I was curious, so I asked Gemini to double-check the figures for me. The calculation showed it was actually 11.7 years of London Underground energy, not just “a decade.” So the original quote was an underestimate. Interesting to see!
